FC Schalke 04 manager Jens Keller could be without Nigerian striker Chinedu Obasi for the rest of the campaign.

For the past three seasons,Obasi has struggled with injuries, which has limited his appearances in the Bundesliga.

Chinedu Obasi has been carrying a 30 centimeter long titanium nail in the left shin, which was broken at the 2010 World Cup.

From a medical point of view, Obasi is healed but he still experiences pains.

The previous plan was for the Super Eagle to undergo surgery in the summer . The surgery is likely to be brought forward because of the pains being experienced.

This season, the 26 - year - old attacker played only 4 matches in the Bundesliga.
